Patented. Aug. 2, 1932 PATENT OFFICE OSCAR I. ANDERSON, OF AURORA, ILLINOIS TEMPEBING MACHINE Application filed October 17, 19:30. Serial No. 489,440.

This invention relates to certain novel improvements 1n tempering machines, and has for its principal ob ect the provision of an "i improved construction of this character which will be highly efficient in use and economical in manufacture.

The salient object of this invention is the provision of an improved machine for tempering springs.

ticularly adapted for tempering coil springs such as are used on railroad cars and the like.

Other objects will, appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings, showing the preferred form of construction and in which:

Fig. 1 is a side elevational view partly in section of a preferred form of construction of T the invention;

30 Fig. 2 is a fragmentary side elevational view showing a part of the machine illustrated in Fig. 1;

Fig. 3 is a sectional view taken substantially on the line 33 in Fig. 1;

Fig. 4 is a sectional view taken substantially on the line 1 1 in Fig. 1;

Fig. 5 is a sectional view taken substantially on the line 55 in Fig. 1; and

Fig. 6 is a perspective view of certain units embodied in the invention.

Referring to the drawings wherein a preferred embodiment of my invention is illustrated, 10 indicates a tank or housing for containing any suitable tempering oil. An

' inlet connection 11 is attached to the tank 10 by means of suitable connecting elements such as the bolt and nut constructions 12 and 13 and provided in the inlet connection 11 is d a pump 14 of any approved type. An outlet connection 15 is provided adjacent the bottom of the tank 10 and suitable cooling coils (not shown) are connected between the inlet 11 and the outlet 15 so that the oil in the tank 10 may be circulated therethrough and properly cooled.

A table 16 is provided at one end of the tank 10 at the top thereof and the table is connected to flanges and 41 provided on the side portions of the tank 10 at the upper side thereof and to a flange-1'. provided at one end of the tank 10 by means of suitable connecting elements such as the bolt and nut constructions 18 and 19. As best shown in Fig. 1, the table 16 extends across a portion of the tank 10 at the top and adjacent one end thereof for a purpose to be described hereinafter.

Extending from the inner end of the table 16 to the opposite end of the tank 10 is a hood 21 which covers a wheel 22, the construction of which will be described presently. The hood 21 includes flange portions 47 and 418 which are secured by means of suitable connecting elements such as the bolt and nut constructions 49 to the flange portions 40 and 41 provided on the side walls of the tank 10. The wheel 22 carries a plurality of pivotally mounted baskets 23. An inlet opening 24 is provided in the end portion of the hood 21 at the end adjacent the table 16 and a discharge opening 25 is provided opposite end portion 51 of the hood.

In the operation of my invention, coil springs 26 are elevated on to the table 16 and rolled forwardly therein through the opening 24 in the hood and thence into the baskets 2321s the wheel 22 is revolved on its shaft through suitable gears 28 and 29 and a driving shaft 30 which is connected to a suitable source of power. As the wheel 22 revolves at a predetermined speed the springs 26 are carried in the baskets 23 through the tempering oil contained in the tank 10. The wheel 22 is rotated in a clockwise direction, as viewed in Fig. 1, and as the baskets 33 containing the springs 26 are rotated through the tank 10 the baskets 23 are dumped individually by means of a resilient trip 31 which is mounted in the end wall 22 of the tank 10 by means of rivets 88 or the like. The springs 26 are rolled on to a slidable shelf 89 of a discharge'table 32 and from the table 32 into a suitable receptacle provided therebelow but not shown. It is apparent that as the heated springs 26 are carried through the oil in the tank the oil will become heated and gases be given off. To allow for the escape of such gases I provide an outlet connection 88 in the hood 21 and this connection includes a flanged base 34 which may be secured to the hood in any approved manner such as by welding.

The shaft 27 is jounnaled in beani-ngs 35 and 36 which are secured by means of bolt and nut constructions 38 and 89 to flanged portions l0 and ell formed on the sides of the tank 10 at the top thereof. Carried by the shaft 27 and keyed thereto by means of pins 42 andS are hubs {hi and i5, Provided on the shaft :27 and keyed thereto by means of pins 52 are spa cing collars '53 and Extending radially from the hub 44- at ,pre determined intervals is a plurality of spokes 55 which include flange portions 56 and these flange portions are secured to the hub 44 by means of suitable connecting elements such as rivets 57. Similar and aligned spokes 58 radiate from the hub 4:5 and these spokes -include similar flanges '59 which are secured to the hub 45 by means of rivets 60 or the like. Connecting linksfil are provided between the spokes 55 and secured thereto by means of rivets 762 or the like. Similar connecting links are provided between the spokes .58. Extending between each pair of aligned spokes 55 and 58 are cross braces68 which are connected to the spokes 55 by means of rivets 164 or the like and to the spokes .58 .by means of rivets or the like. Extending between each aligned pair .of spokes 55 and 58 are braces 66 which are secured to the spokes 55 by means of rivets 67 or .the like and to the spokes .58 by means of rivets 68 or the like.

The baskets23 include ear portions 69 and 70 in which .are provided openings 71 and-72. A block 78 is provided cneac'h of the spokes 55 and a. similar block 745is disposed on each interiorly of the 'blocks '78 and 74 of the spokes 58. Formed in the blocks 78 and 74 are openings 75 and 76 and aligned XR "i'thtliBSG openings are similar openings 77 and 78 in the spokes 55 and {58, respectively. In mounting the baskets 28 for pivotal movement a suitable connecting element such as threaded bolt '79 is inserted through each of the ear portions 70, through the open-ing'77 in the spoke 5'5, and through the opening in block 73. The bolts 79 are preferably somewhat smaller in diameter thanthe openings in the ear portions 70 of the baskets so as to allow the basket 23 to swing thereon. As shown in Fig. '6, a similar bolt 80 "is inserted through the opening 71in the ear.69, through each ofthe'openings 78in the spokes 58, through the opening 76 in the block '74. Suitable nuts (not shown) are provided on the threaded portions ofthc bolts 79 and 80 It is manifest, therefore, that the baskets 23 are mounted for swinging movement on the bolts 7 9 and 80. A plurality of spaced apart openings 81 are provided in the baskets 23 so that oil may drain therefrom as the baskets are rotated upwardly of the trip 31.

The shelf plate 89 includes arm portions 82 and.83 in :which slots 84; ;and 85are provided and similar slots are provided in the -table32. As in Figs. 1 and 5, the shelf plate 8,9 is adjustablynnounted for sliding move ment on the discharge table 32 by means of vsuitable bolt and nut constructions 8(3 and 87 which are inserted in the slots 84 and 85. By refenninguto Fig. :5it .may be seen, therefore, that the shelf 89 may be adjusted so as to project into the "hood 2'1 any desired distance. The table '32 isniounted on theendwall 9 of the tank 10 by meansof a downwardly depending portion 86 and rivets 97 or the like. The outer end of thetable 32 is supported on a housing 90 which provides a trough 941m d this h ousi-ng ;may be secured to the end wall 22 in any approved manner such 21s by welt-1- ing. The table 32 includes upstanding aflange portions -9-1 and 92 to provide guides for 'the springs 2611s the springs q ollofi' the tgible 32. A plurality of openings -'98 :are provided in the table 32 to permit drainage of oil from the springs therethrough into *the trough 94: and thence into the tank '10 through an opening 95 provided in the end :wall 22. Ancilset portion 98 is pnovided in the honsing 90 and a screen 99 is mounted '0I1ftl1'lS-Ofi S8t:p0I- tion 98 and secured {to :the portion 96 in any approved manner. eIt will be apparent, therefore, that oilcanried by :the springs '26 on to the shelf 89 and tahler32 \willdrainthrough the openings '93, through the screen 99 into the trough :94- a-nd thence into the :tank *10 through the opening 95.

A suitable source of power such as an electric motor isiconneoted to :the shaft 30 in eny approved manner and itis manifest that as the shaft 30 is rotated the gear thereon will drive gear '28 and ishaif 27, ,A suita le timing :dem'ce not shown, anav he provided for rotating the wheel 22 and attachedibaskets 2.3 a any desired p d which is dependent on the material of which the springs to be emp r d a a ad th hea impr n e ther to in the heating operation preceding tem.- n r nsn h ki a i aw d, tc-i as is Well understood in the art.

It is manifest, thenefone, that as the i vheel 22 is rotated and thesp-nings 526 such as for exam ple !t1h CQl1:Sprl:IlgS aised on nai-lwayi-ears. are elevated onto the table lfi, {these springs may be rolled through :the opening 24 in the hood into the baskets Q3 and it will be seen that as the baskets 28 are rotated. clockwise on the wheel 2 they move :the springs 26 through the oil in the tank 10 at a rate of speed which can be determined to suit the needs of conditions. As the baskets 28 and springs 26 held therein are rotated upwardly the baskets are selectively dumped by the trip 31, as best shown in Fig. 2, thereby allowing the springs 26 to roll out onto the inclined shelf 89 and thence over the table 32 and into a suitable receptacle (not shown) which may be provided below the lower end of table From the foregoing description of my in-- vention it is manifest that I have provided an improved machine for tempering coil. springs and the like which while efiectively' accomplishing its other objects as pointed outhereinbefore will be simple and economical in construction and highly efficient in use.
